Filed: 1994-12-28
Granted: 1998-11-17
Abstract: An ignition timing control system for an internal combustion engine that estimates the octane number of the fuel being used based on the state of engine combustion knocking and controls the ignition timing to a value not exceeding the knocking limit.  The basic ignition timing is set along the knocking limit of fuel having least octane number and the maximum advance amount is set between the knocking limit and the second knocking limit of fuel having maximum octane number.  Octane number is estimated from the occurrence of knocking. On the other hand, upper limit of the estimated octane number is set based on the MBT of the engine such that the estimated octane number is limited with the upper limit.  Advance rate is determined based on the estimated octane number and is multiplied to the  maximum advance amount to determine an ignition timing correction amount.  The ignition timing is finally determined from the basic ignition timing and the ignition timing correction amount.  A learning control is conducted for the octane number estimated and the estimated octane number is limited within the learned value.

Title: System for producing time-independent virtual camera movement in motion pictures
Inventor: TAYLOR DAYTON V
IPC: H04N7/00
Filed: 1995-12-05
Granted: 2007-03-13
Abstract: A system for producing virtual camera motion in a motion picture medium in which an array of cameras (10) is deployed along a preselected path with each camera (10) focused on a common scene (12). Each camera (10) is triggered simultaneously to record a still image of the common scene (12), and the images are transferred from the cameras (10) in a preselected order along the path onto a sequence of frames in the motion picture medium such as motion picture film (20) of video tape. Because each frame shows the common scene (12) from a different viewpoint, placing the frames in sequence gives the illusion that one camera (10) has moved around a frozen scene (i.e., virtual camera motion). In another embodiment, a two-dimensional array (1100) of video cameras (1102) is employed. Each camera (1102) synchronously captures a serie of images in rapid succession over time. The resulting array of images can be combined in any order to create motion pictures having a combination of virtual camera motion and time-sequence images.
